pip install cx oracle python 3

cx_Oracle is a Python extension module that enables access to Oracle Database. It allows Python programs to connect to Oracle Database, execute SQL statements, and fetch results. This tutorial will guide you through the process of installing cx_Oracle for Python 3 using the pip package manager.
Before you begin, ensure that you have the following:
cx_Oracle requires the Oracle Instant Client libraries to connect to an Oracle Database. Follow these steps to install the Oracle Instant Client:
Visit the Oracle Instant Client Downloads page.
Download the Oracle Instant Client Basic package that matches your operating system (e.g., Basic Light, Basic, or Basic OIC).
Extract the downloaded zip file to a directory of your choice.
Add the Instant Client directory to your system's PATH environment variable.
Once you have the Oracle Instant Client installed, you can proceed to install cx_Oracle using pip. Open a terminal or command prompt and run the following command:
This command will download and install the latest version of cx_Oracle from the Python Package Index (PyPI).
After the installation is complete, you can verify that cx_Oracle is installed correctly by opening a Python interpreter and trying to import the module:
If there are no errors and the version is printed, then cx_Oracle is successfully installed.
Now that cx_Oracle is installed, you can use it to connect to an Oracle Database. Here's a simple example:
Replace the placeholders (username, password, hostname:port/service, and your_table) with your Oracle Database credentials and the SQL query you want to execute.
You have successfully installed cx_Oracle for Python 3 and connected to an Oracle Database. You can now build upon this foundation to interact with your Oracle Database using Python. Explore the cx_Oracle documentation for more advanced features and capabilities.
Happy coding!
